SKF Multilube pumping unit
Compact and flexible solution
All relevant components and functions are
integrated into the modular SKF Multilube
pumping unit: control unit, pump, reservoir,
directional valve and pressure monitoring.
Built-in heating enables operation even
under demanding and cold conditions.
SKF Multilube can be used with all SKF
grease and oil systems, SKF MonoFlex single-
line, SKF DuoFlex dual-line, SKF ProFlex
progressive lubrication systems. Auxiliary
equipment, such as sliding surface nozzles
and lubrication brushes, can be used de-
pending on lubrication needs.
SKF centralised lubrication systems are an effective solution for lubricating individual
machines and equipment. The systems are easy to install, the pumping unit has a compact
structure, the metering devices operate reliably and the system is simple to use. As a result,
machine applications that use this system are much more reliable even in harsh outdoors
operating conditions.

The integrated user interface
The SKF Multilube pumping unit is con-
trolled by a built-in user interface, which
makes it simple to use the system and
adjust its functions.
It is also possible to control the system
externally with SKF multi-channel con-
trol centres, or a customer’s PLC or pro-
cess control system. Remote monitoring
and control can also be achieved using
text messages by creating a connection
between an optional modem which is in-
stalled on the pumping unit and a mobile
phone.
SGA metering devices
Lubricant greases NLGI 000 – 2
SGA dosage range 0,15 – 8,6 g
Designed for use in dual-line lubrication
systems, SGA metering devices feature a
modular design with separate baseplates
which make system modifications simple.
SGA metering devices are manufactured of
zinc coated carbon steel or stainless steel
and are installed in either aluminium or
stainless steel BPSG baseplates. There are
three sizes of metering devices and six base-
plates, covering all industrial needs from
small joints to large roller bearings.
SKF DuoFlex lubrication systems with SGA metering devices
Centralised lubrication improves runnability
The high SKF standards for automatic lubrication systems virtually prevent bearing failures and improve the runnability of machines and
equipment. The SKF Multilube pumping unit provides optimal lubrication results and reduces energy and lubricant consumption at the same
time. The SKF centralised lubrication system is also a financially justified solution for lubrication to improve the runnability of production
processes.

SKF ProFlex lubrication system with progressive metering devices
The VPB/VPK progressive metering devices used in SKF ProFlex systems can also be used in
centralised manual lubrication systems. Metering devices are manufactured of zinc coated
carbon steel. There is also available two channel/zone ProFlex system. For additional infor-
mation regarding progressive metering devices, please refer to SKF brochure PUB 1-3017,
Block feeder VPB, Block feeder for use in oil or grease lubrication systems.
OS-33 metering device, lubrication felt and sliding surface nozzle
Lubricant oil
OS dosage range 0,3 – 2,6 cm3
Metering device sends a dose of lubricant to
the lubrication felt, which stores lubricant
before releasing it to the lubrication point.
Felt can be easily cut with scissors to the
right shape and width for the lubrication.
The metering device sends a dose of lu-
bricant to the sliding surface nozzle, which
divides the dosage to the sliding surface. The
sliding surface nozzle is equipped with a
check valve which blocks the lubricant flow
back to the metering device.
SKF MonoFlex lubrication system with OS metering devices
OS-33 metering devices are installed on separate BPOS- mounting rails which are made
from aluminium and available in six different sizes. OS-33 metering devices are externally
adjustable. Metering device are made from zinc coated carbon steel.

!Important information on product usageAll products from SKF may be used only for their intended purpose as described in this
brochure and in any instructions. If operating instructions are supplied with the products, they must be read and followed.
Not all lubricants are suitable for use in centralized lubrication systems. SKF does offer an inspection service to test customer supplied lubricant to determine if it can be used in a central-ized system. SKF lubrication systems or their components are not approved for use with gases, liquefied gases, pressurized gases in solution and fluids with a vapor pressure exceeding normal atmospheric pressure (1 013 mbar) by more than 0,5 bar at their maximum permissible temperature.
Hazardous materials of any kind, especially the materials classified as hazardous by European Community Directive EC 67/548/EEC, Article 2, Par. 2, may only be used to fill SKF centralized lubrication systems and components and delivered and/or distributed with the same after consulting with and receiving written approval from SKF.
